This invention relatesto a washing apparatus particularly for hollow receptacles such as glasses, tankards, mugs, cups, milk bottles, jars and the likewhich washing, apparatus is of the kindcomprising an upright core'having a number of flexible elements radiating'fromit along the length thereof and which co-operates with a number of inwardly-directed flexible elements supported at their outer ends.

According to this invention, a washing apparatus of the. kind" referred to-is characterized in that said layers are separately and detachably mounted on a frame comprising a number of arms extending upwardly from and connected to a suction cup to which is also secured said upright core.

In one form of constructiongeach of said layers' has-its peripheral'edge clamped to a rigid ring attached to said upwardly extending arms. For example, each of said layers has its peripheral edge bent over said rings and secured thereto by a contractible clamping ring.

The flexible elements on the core may be arranged to extend into the spaces between the aforesaid layers.

The flexible elements on the core may also be formed from a number of sheets of resilient material, each having an aperture the periphery of which is sprung into circumferential grooves formed in the core.

The core may be attached to the aforesaid frame and may be provided at its base with a buffer.

The following is a description of one form of the invention suitable for washing tumblers and tankards, reference being made to the accompanying drawings, in which:

Figure 1 is a part ide elevation and part sectional view of the apparatus, and

Figure 2 is a plan view.

The frame of the apparatus comprises three metal uprights H] which are encircled by three cylindrical metal rings l I which are spaced apart and secured to the uprights as by welding, brazing or sweating. The lower ends Ill of the uprights are bent inwardly and secured at their extremities, as at l2, to a metal disc l2. A suction cup 13 is secured to the metal disc by a washer l4 and screws 15. A core I6 is provided with a number of circumferential grooves H, the lowermost one of which accommodates a bellshaped buffer IS. The core is secured to the aforesaid metal disc by a set-screw l9. The periphery of the bell-shaped buffer is provided with slots 20 through which the inwardly-bent ends of the uprights extend.

Each of the aforesaid cylindrical r-ingsl l 'has bent-over it theperi'p-heries of a sheet of rubber M- which is secured in position by a clamping ring z2 'h'aving lugs 2 3 at its end whichisengaged bya clamping screw- 28; As will be seen from Figure 2, each flexible disc is cut top'rovide a number of inwardly-directed wedge-shaped finger-s' 24 separated by slots 25''; which fingers terminate to provide-an apert'ureZG throughwhich the aforesaid coreex-tend's. The periphery of; the discsmay be provided with slots 21 through which the uprightsextend.

As already indicated, the core isprovided with a number. of circumferentialgrooves and in each of-the'grooves is mounted a sheet of rubber 30 having a: central aperture the marginal portions of which may be sprung into the-groove and each having outwardly-directed resilient fingers 29.

Certain of these grooves in thecore are so disposed that the'outwardly-radiating fingers; are located between the aforesaid'resilientdiscs.

The uppermost groove has slots extending axially from its upper wall out through the end of the core, and the groove in addition to accommodating one of the aforesaid sheets of material 30 also accommodates a number of resilient elements 3| which have apertures therein which encircle the sector formed between the grooves and the axially-extending slots, which resilient elements extend above the top of the core and are shaped to provide a number of fingers 33.

We claim:

1. A washing apparatus comprising a suction cup adapted to cling to the vessel in which washing is to be carried out, an upright core and a number of upright arms spaced away from the core all secured to said suction cup, a number of flexible elements at different levels on said core, a number of discs of flexible material encircling said core and having flexible elements directed towards said core, a rigid ring clamping substantially the whole periphery of each said disc and means for detachably securing said rings to said arms, each said disc at its periphery being folded over a rigid ring.

2. A washing apparatus comprising a suction cup adapted to cling to the vessel in which washing is to be carried out, an upright core and a number of upright arms spaced away from the core all secured to said suction cup, a number of flexible elements at different levels on said core, a number of discs of flexible material encircling said core and having flexible elements directed towards said core, a number of rigid rings secured to said upright arms, one for each said disc, substantially the whole peripheries of which discs are folded over the edges of said rings and are cut away opposite said arms, and clampin rings for securing the whole of said folded-over portions to said rigid rings.

3. A washing apparatus comprising a suction cup adapted to cling to the vessel in which washing is to be carried out, an uprightcore and a number of upright arms spaced away from the core all secured to said suction cup, a number of rigid rings secured to said arms at difierent levels, a number of flexible elements at different levels on said core, a number of separate discs of flexible material encircling said core secured around the whole of their peripheries to said rings and having flexible fingers extending towards said core, each said disc at its periphery being folded over a rigid ring, and means for detachably securing said rings to said upright arms, which flexible elements on said; core are arranged to extend into the spaces between the discs. 7

4. A Washing apparatus comprising a suction cup adapted to cling to the vessel in which washing is to be carried out, an upright core and a number of upright arms spaced away from the core all secured to said suction cup, a number of rigidrings detachably secured to said arms at different levels, which core is provided with a number of circumferential grooves spaced apart along it, a number of sheets of flexible material having apertures the edges of which are accommodated in said grooves, a number of separate discs of flexible material encircling said core secured around the whole of their peripheries to said rings and having flexible fingers directed towards said core, each said disc at its periphery being folded over a rigid ring.

5. A washing apparatus comprising a suction cup adapted to cling to the vessel in which wash- 4 their lower ends, which portions and core are all secured to said suction cup, a number of flexible elements at difierent levels on said core, a number of discs of flexible material encircling said core and having flexible elements directed towards said core, a rigid ring clamping the periphery of each said disc and means for detachably securing said rings to said arms, each said disc at its periphery bein folded over a rigid ring.
